STAMPED METAL WHEEL.

Application filed May 12,

To all whom it may concern Be it known that I, LEWIS FINE, a citizen .ofthe United States, residingat Philadelphia, Pennsylvania, have inventedcertain new and useful Improvements in Stamped Metal Wheels, of which Ideclare the following to be a full, clear, and exact de scriptlon.

:This invention relates to improvements in metal wheels,.particularly ofthe type adapted to be employed in connection with trucks, tractors, andthe like.

One object of the invention is to provide a wheel of this characterwhich is of strong. but simple construction and efficient in operation.

A further object of the invention is to provide a metal wheel of thedisc type hav- 1ng an improved arrangement of bracing elements forspacing the disc sections from each other.

A- further obi'ect of the invention is to provide a whee of thischaracter havin improved means for supporting the rim and retaining thesame in position upon the wheel discs.

A further object of this invention is to provide a wheel of thischaracter having certain improved details of construction andarrangement of the parts, which will be more fully describedhereinafter.

Further objects of this invention relate to economics of manufacture anddetails of construction, as will hereinafter appear from the detaileddescription to follow.

The objects of the invention are accomplished in one instance by thedevices and means described in the following specification, but it isevident that'the same may be varied widely without departing from thescope of the invention, as pointed out in the appended claims.

A structure constituting one embodiment of the invention, which may bethe preferred, is illustrated in the accompanying drawing forming a arthereof, in which:

Figure I is a si e elevation of a wheel structure, embodying the presentinvention, having a portion thereof broken away. I

and illustrating the relative position of the spacing rings with respectto each other and the hub.

Referring to the drawing, similar reference characters designatecorresponding parts throughout the several views, and the sect onalviews are taken looking in the directlon ofithe small arrows at the endsof the section lines.

In the embodiment of the invention illustrated herewith, 10 designates ahub provided with an outwardly extending annular flange 11 formedintegral therewith and positioned adjacent one end of the hub. A pair ofwheel discs 12 and 13 of similar construction are each provided with acentral opening formed of such a size as to fit over the outercylindrical portion of the hub member when assembled in positionrelative to each other. Cutaway portions 14 of similar size and shapeare formed in the wheel. discs intermediate the portions of the discswhich fit over the hub and the outer peripheral portions thereof, thesecutaway portions being formed ,-in the discs in a manner as to registerwith each other when the discs. are in assembled position, and sopositioned relative to each other as to provide radially extending spokeportions 15 positioned between adjacent cutaway portions and extendingoutwardl from the central portion of the wheel discs towards theperipheries thereof. Lock bars 16 provided with outwardly extending edgeportions 17 and 18 are positioned within the cutaway openings 14 formedin the wheel discs, and when the various parts of the wheel structureare properly assembled, the outwardly extending edges 17 and 18 of thelock bars are bent over the outer surfaces of the wheel discs adjacentto the cutaway portions in such a manner as to form flanges engaging theouter surfaces of the wheel discs' and assisting in securing the sameproperly in position relative to each other. Each of the wheel discs isprovided with an offset peripheral edge portion comprising a part 19oflset'from the original plane of the disc, and an outwardly extendingpart 20 located in a lane substantially parallel to the original-p aneof the disc, the portion 20 terminating in a beveled edge 21 formed fora purpose which will be more fully described hereinafter.

A pair of annular plates 22 and 23 are positioned between the wheeldiscs adjacent the hub portion of the wheel in such a'manner as to bearagainst the wheel discs 12 and 13 respectively. The inner and outerspacing rings 24 and 25 are positioned between the Wheel discs adjacentthe hub portion of the wheel and concentric with the axis .thereof, thesaid spacing rings 24 and 25 being provided with reducededge portionsfitting against'correspondingly formed edge portions upon the annularrings 22 and 23 in such a manner as to produce a rigid bracing structurefor properly spacing the wheel discs 12 and 13 from each other, andassisting in retaining the same in proper relative position. A brakedrum 26 provided with an inwardly extending annular flange 27; ispositioned upon the inner end of the hub member in such a manner thatthe inwardly extending annular flange 27 bears against the outer surfaceof the wheel disc 13 adjacent the central portion thereof, and the brakedrum, wheel hub and wheel discs are firmly secured together by means ofbolts 28, or other suitablesecuring means ssed through registeringopenings form in the annular portion 11 of the wheel hub, the brakedrum, the wheel discs and the annular lates. I

A p urality of T-shaped cross braces 30, each of which is provided witha main outwardly extending web portion 31 and a pair of oppositelyextending flanges 32 formed upon the ase portion thereof, are supportedby the out-turned portions 19 of the wheel discs and spaced from eachother throughout the circumference of the wheel. A rim 34 is providedwith grooves 35 formed upon the inner surfaces of the side edgesthereof, and the rim 34 is preferably shrunk upon the outer surface ofthe wheel in such a manner as to bear against the outwardly extendingportions 31 of the T-shaped cross braces, an have the (grooves 35 formedtherein register with an fit over the beveled edges 21 of theperipheraled e portions of the discs so as to be firmly c amped in engagementtherewith and prevent the rim.

fromfbecoming disengaged from the outer surface of the wheel.

It will be understood from the above desription that "the spacing rings24 and'25, together with the annular plates 22 and 23 co-operatingtherewith, provide a simple and efficient form of spacing means adaptedto be positioned between a pair 9f wheel discs in such a manner as toproperly space the same from each other, and these arts co-operate withsecuring bolts 28 to orm a firm and rigid wheel structure wherein thewheel discs are properly spaced from each other and securely attached tothe wheel hub.

' The lock bars 16, when secured in position between the wheel discswith the opposite discs in proper the wheel edge (portions 17 and 18bent outwardly over the e gee of the portions of the-wheel discs formeby the cutaway openings, serve as an additional spacing means forspacing the discs from each other, and also serve as an additionalmeansfor securingthe wheel discs in osition relative to each other. Therim 34 is preferably shrunk upon the outer portion of the wheel in sucha manner as to fit tightly thereupon, and the co-operating beveled edgeportions of the disc and the ooves formed in the rim register with eacother in such a manner as to provide apositively acting securing meansfor retaining the rim upon the outer surface of the wheel. The

securing bolts 36 passed through the pe-' ripheral edge portions of thewheel discs and spaced from each other throughout the circumference ofthe wheel serve to secure the outer peripheral portions of the wheelsition relatively to each other and draw t cm into close contact withthe ends o-f'the cross braces so as to assist in firmly securing thebraces in position within the eripheral edge portions of the disc.

T e wheel structureythus formed has the various portions thereofsecurely braced together in such a manner as to form a firm and rigidstructure, which is capable of withstanding the various strains to whichit is liable to be subjected, while the various parts are capable ofbeing readily formed and assembled in position to make the completedwheel. f

While I have shown and described in considerable detail 'a specificembodiment of my invention, it is to be understood that this showing anddescription is illustrative only, and for the purpose of rendering myinvention more clear, and that I do not regard the invention as limitedto the details ofconstruction illustrated or described, nor any of them,except-in so far as I have. included such limitation within the termsof'the following claims, in which it is my intention to claim allnovelty inherent in my invention broadly as well as specifically.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:
